I am taking my old engine apart, but now I need a tool to get the bolts for the connecting rod bearing caps out. They have 12-point heads, I couldn't find a socket size in the RAVE. What's the socket size for these 12-point bolts? Thanks.

 

OK, I figured that out. Measured the bolt and compared it to the drawing on McMaster. It is a 10mm socket. Ordered one with a 1/2" drive and it works.
